' Application filed March 25, 1922, Serial No. 546, 751. Renewed April 4, 1925.

The invention relates to drink mixers.

In machines'for this purpose, the liquid constituents of the drink to be mixed are usually poured into a receptacle. WhlCll s generally designated a shaker, from many different containers disposed away from the mixer. uents therein is brought to the mixer and placed in operative relation thereto and 1s removed from the machine after each mixing operation, to discharge its contents. This is rendered necessary, because so'many d fferent in redients and flavors are used 1n making rinks that they are, in nearly all cases, mixed individually. It is usually necessary to run the agitator for a conslderable period to properly blend or mix the constituents and, therefore, it is desirable that.

provision be made for retaining the receptacle and agitator in operative relation to permit. the dispenserto perform other duties during the mixing operation. In drink mixing, it thus becomes necessary to frequently place the receptacle containing the constituents into cooperative relation to the agitator and to withdraw it from the machine to discharge its contents and cleanse the receptacle between mixing operations.

A desideratum in this art is to expedite and simplify the operations necessary to bring the receptacle and agitator into cooperative, relation, to maintain them in such relation, in starting and stopping of the motor and the removalv of the receptacle. Heretofore, in machines whereof I am aware (excepting in those exhibited in concurrently pending applications), it has been necessary in their use to manually manipulate the receptacle into operative osition and withdraw it therefrom and to a ditionally perform some separate step 'or operation, such as lowerin the motor and agitator together, or shifting the agitator and its shaft into the receptacle and relatively to the motor, or raising and looking a receptaclesupport to establish and maintain cooperative relation of the receptacle and agitator or to control the operation of the machine. Another desideratumin this art is tosimplify the machine by dispensing with movable connections in and for the driving mechanism-for the agitator.

One object of the present invention is to provide an improveddrink mixer in which these additional operations or steps are dis- The receptacle with these constit-,

pensed with and in which manual shift of trol the operation of the machine and to sethe receptacle is utilized to completely concure it and the agitator in cooperative relation. By dispensing with the necessity of these additional steps or operations, the time of the dispenser in performing them is saved and the serviceis improved.

Another object of the invention is to provide an improved drink mixer in which rovision is made for the ready removal an replacement of the motor and all of itselectrical connections. In practice, it has been found that the motor andelectrical connections therefor sometimes get out of order, while the remaining mechanism does not. When motor or electrical repair is necessary, it has been customary to send the entire machine to the repairshop. The present invention contemplates mounting the switch directly on the outside of the motor casing, so that when the motor is removed, all electrical connections will remain attached thereto, so that another motor with connections may be readil substituted while the repairs are being ma e in the shop, without the necessity of making any electrical connect-ions at the machine.

Another object of the invention is to provide a receptacle-operated machine, in which the rece tacle, during the mixing operation, is yieldingly held between bottom and top supports. Other objects of the invention will more fully appear from the following description.

The invention consists in the several novel features hereinafter set forth andjmore particularly defined by claimsat the conclusion hereof.

In the drawings: Fig. 1 is a side elevation of a machine embodying the inventon, the receptacle-holder being shown in lowered or I idle position. Fig. 2 is a plan, the cover of the switch-box being shown in section. Fig.

3 is a section on line 3-3 of Fig. 1. Fig 4 is a vertical section of the machine. the receptacle being shown in operative position. Fig. 5 is a detail showing the manner of locking the carrier to secure the receptacle in its operative position. I

The invention is exemplified in a machine comprising an electric motor 1-0 to the rotor of which is secured a pendant shaft 11 with an agitator 12 fixed to its lower end; a sup-' port framework comprising a base 9 adapted to rest on a table or counter, a pair of separated vertical rods or standards 13 having their lower ends fixedly secured in said base, and a bracket 16 in which the upper ends of rods 13 are secured and which is provided.

with lugs 14 to which the casing of the motor is removably secured by screws 14; and a 1 box 15 containing a switch for controlling the operation of the motor. Shaft 11 is of suffi cient length so that the agitator will reach .into the constituents of a drink to be mixed near the bottom of an open-top receptacle a ship between the agitator and the motor orheld below the motor. There is sufficient clearance below and around the agitator to permit the receptacle to be placed thereb'eneath without spilling its contents and without lowering the agitator into the receptacle so that it is not necessary to vary the relationbetween the agitator and the machine base in establishing cooperative relationship between the receptacle and the agitator.

In the present invention, a carrier in which the receptacle is looked is vertically slidable on the standards 13 and com rises a standard 17, a lower cross-member 1 which is provided with holes 17 through which the rods 13 pass, and an upper cross-member 18 which isprovided with holes 18 rods also pass. Lugs 20- are formed on the rear portion of the rods 13 directly behind.

notches 19 in the front of the rods and-are -adapted'to engage and support the crossmember 18 to lock the carrier in its raised position. The portions 20 of the rods which are above the notches 19 operate as stop lugs and limit the upward movement of the carrier. A

bottom-support 22 for the receptacle a, which may be an ordinary glass tumbler if desired,

'is adjustably secured to the standards 17 by so that its central portion will extend into the receptacle and tend to position the glass around the agitator and hold it against lateral movement. The upper holder 25 is provided at its back with downturned lugs 27.

which are pivotally connected by a pin 28 to lugs 29 on a bracket 30 which is adjustably secured to standard 17 by screws 31 and slots 32. The purposeof the adjustable connection between said bracket and standard is to permit the holder-member 25 to be adjusted for receptacles of difierent heights. The

spring 33 is coiled around pivot-pin 28 and is applied to press the holder 25 downwardlyv the upper edge of the receptacle. A

through which said stop-arm 34 is provided to limit the downward movement of the holder so that it will be positioned to permit the receptacle (1 to be inserted between support 22 and the holder;

The central portion of support 22 is .flared downwardly,'as at 22*, cle onto said support. This holder member 25, as shown in the drawing, fits against the rim of the receptacle and extends inwardly thereof so that it functions also as a springpressed cover, it being understood that in practice the vortex causes the highest portion to guide the receptaof the liquid column to be adjacent the wall ofthe receptacle. 1

The switch-box 15, formed of insulating material, is securedby screws 35 directly to the outside of the casing of motor 10 and comprises a cover 36 which is removably. secured thereto by screws'37'. Conductor strips 38 and 39 project from one side of the box and are adapted to enter a switch-socket of usual construction and to which a flexible conductor-cord is usually connected. Strip 39 is provided with a lug 40 whichv is secured in the box by a screw 41; A conductor 42 leads from said screw to one end of the motorwindings. A conductor 43 leads from the other end of said windings to a screw 44 which secures a switch-contact 45 in the box.

A strip 38 is provided witha lug 46 which contacts with a spring-contact strip 47 and both ofsaid stri s are securedv in the box by screw 48. A utton 49 is slidably held in the box and is connected to contact-strip 47 by a screw 50 which is adapted, when the button is raised, to engage .with the undercured to the supportingrods 13 and the upper end of said lever is provided with; a camsurface 53which is adapted to engage switchbutton 49 to force it upwardly to close the side of resilient contact 45 to close the circuit circuit for the motor. A cam 54 on said lever is adapted to be engaged by the upper cross- 1 member 17" of the receptacle-carrier holder to force the lever backwardly while the receptacle is being lifted into its operative position and to hold it while the carrier is raised, and to permit the lever to be retracted by a spring 56 during the lowering of the receptacle for withdrawal fromthe machineJ The operation of the machine will be as -follows: Normally, the carrier will be in lowered position shown in- Fig. 1. The operator, grasping thereceptacle, will place its upper end under the spring-pressed holder member 25 and swing its lower portion backwardly onto the bottom-support 22 and then lift the carrier through the receptacle until the carrier slips over locking lug 20. Thereupon, the carrier will be locked to holdthe receptacle in its operative position, as shown in Fig. 5. During the upward shift of the carrier, lever 51 will be operated to close the switch and cause the motor to' drive the agitator. During the operation of the motor, the receptacle will be gripped and centralized between the bottom support 22 and the yielding upper member 25. After the mixing operation has been completed, the o erator will grasp the receptacle and force it ackwardly sufliciently to disengage the carrier from the lug and then lower the receptacle. While the carrier is locked in operative position, it will hold the lever 51 in position-to keep the switch closed. During the descent of the carrier, the switch-lever will be released by the carrier and retracted by spring 56 to open the switch and stop themotor.

The invention exemplifies a drink mixer which is controlled by manual placement and removal of the receptacle into a holder com--' prising top and bottom members between which the 'receptaclewill be resiliently.

gripped, and in which provision is made for adjusting the bottom support for the receptacle relatively to the agitator; in which the switch-box for controlling the motor is secured on the outside of and to the motor casing, so that all the electrical connections are removable with the motor for convenience in making repairs and substitution of one motor for another; in which the switch-box is provided with strips adapted to engage directly with a switch-socket so that no flexible cord is necessary on the machine; in which the motor support is made up of rods secured together and upon which the receptacle-holder is is adapted to slide. Theinvention is not tobe understood as restricted to'the details set forth, since these ,may be modified within the sco e of the appended claims, without departing from the spirit and scope of the invention.
